Title: A process for polymerising organosilicon compounds
IPC: C08G77/08
Filed: 1961-03-15
Abstract: Homo- or copolymers are made by heating one or more cyclotrisiloxanes of the formula <FORM:0910440/IV(a)/1> and 0 to 10 mol. per cent of one or more cyclotrisiloxanes of the formula (R21111SiO)3, in contact with a catalyst selected from R112CXCOOX, R11CH2.CO.CXR11COOR111, XCH[COOR111]2, XCH[COOX]2, <FORM:0910440/IV(a)/2> <FORM:0910440/IV(a)/3> (CHXCOOR111)2 and (CHXCOOX.)2 and in amount such that there are from 0,5 to 1,000 alkali metal atoms alpha to a carbonyl group per 100,000 Si atoms, in the above formulae each R is a perfluoroalkyl radical of 1 to 10 C atoms, each R1 and R1111 is a monovalent hydrocarbon radical, each R11 is H or a monovalent hydrocarbon radical of 1 to 6 C atoms, each R111 is an alkyl radical of 1 to 5 C atoms, and each X is an alkali metal atom.  The cyclic siloxanes may be made by the methods described in Specification 832,487.  If desired the cyclic siloxane can be copolymerized with up to 10% mol. of one or more cyclics containing methyl, vinyl or phenyl radicals, as described in Specification 832,488.  Polymerization can be effected, if desired in the presence of solvents, at temperatures of from 30 DEG  to 250 DEG C. for times varying from 5 minutes to 3 days.  In a typical example (1) a copolymer, obtained by heating at 150 DEG C. for 1 hour a mixture of [CF3CH2CH2Si(CH3)O]3, [(CH3)(C2H3)SiO]3 and a -sodio sodium acetate, was compounded with fume silica, silica xerogel, a hydroxy-terminated dimethylpolysiloxane, ferric oxide and benzoyl peroxide, and heat cured to an elastomer.  Specifications 722,482, 832,489 and U.S.A. Specification 2,918,494 also are referred to.ALSO:Esters and salts of certain carboxylic acids containing an alkali metal attached to a C atom alpha to at least one carbonyl C atom, may be made in known manner by reacting an acid salt, e.g. R112CH.COOX (R11 = H or a monovalent hydrocarbon radical, X = an alkali metal atom), with a stoichiometric amount of an alkali metal amide at 170 DEG  to 250 DEG C. in a system flushed with nitrogen.  The a -alkali metal derivatives of acetoacetic ester are best made by reacting an alkali metal or alkali metal amide with a suitable carboxylic acid ester, while the malonic ester derivatives are best made by reacting the ester with an alkali metal alkoxide.  The a -alkali metal derivatives of the alkali metal salts of malonic acid are best made by reacting the salt with the desired alkali metal amide as described in U.S.A. Specification 2,918,494.  Several a -alkali metal derivatives are disclosed.  In Example (7), NaCH(COOC2H5)2 was made by adding Na to a solution of malonic ester in the dimethyl ether of ethylene glycol.

In a circuit adapted to amplify a small part only of a relatively large input signal, comprising an amplifier having a resistance connected in series between the input terminal of the circuit and an input terminal of the amplifier and a negative feedback resistance connected between output and input terminals of the amplifier, a further negative feedback is connected between the output terminal and an intermediate terminal of the amplifier, the further feedback circuit including a pair of oppositely poled unilaterally conducted devices adapted to increase the amount of the further feedback when the signal is outside the given small range. Fig. 2 shows a "see-saw" type amplifier comprising a series input resistor 3 and a feedback resistor 4. A further feedback path is provided through a pair of oppositely directed biased diodes 15, 16 arranged to conduct when the signal extends beyond a given voltage range so that the feedback is greatly increased and the gain greatly reduced. The position of the range over which the diodes are non-conducting may be varied by adjusting the voltage on the grid of a valve 6. The Specification also describes a known alternative circuit in which the diodes are connected effective across the feedback resistor 4 instead of in an additional feedback path and in which the range of non-conduction of the diodes is varied by a bias voltage fed to the grid of valve 5.

Title: Device and method for measuring material flow containing products characterized by unfavourable fluidal features
Inventor: NAEF PETER
IPC: B01F25/90
Filed: 1991-08-22
Abstract: The invention concerns a continuous mixing and homogenization unit for, in particular, mill products. The system ensures in particular that all the raw materials are mixed together simultaneously in a pre-mixing chamber (8) in order that the subsequent homogenization takes place continuously to the highest specifications. The raw-material  weighing device (4) used, as well as the worm conveyor (25) for removal of material from the weighing device, are designed as substantially tube-shaped units and together form a differential throughput-control system (6). Throughout the whole system, the inside wall in contact with the material is thus tubular and subject to a continuous cleaning action by virtue of the movement of the material. It is also possible to use several weighing devices (4) located symetrically round a collection point (17), for different components. The quality of mixing is extremely high.
